Table 1.
Mass balance of fractions obtained by processing approximately 100 kg of blue mussels (results of a representative process performed in triplicate in 2008).
| Fractions | Wet weight (kg) | Dry weight (kg) | Mass balance A (%) |
|---|---|---|---|
| Crude extract (1:1) | 150 | 82.85 | 100 |
| Solid after sieving | 73.50 | 58.87 | 71.06 |
| Liquid after sieving | 190 | 10.05 | 12.13 |
| Solid after centrifugation | 21.75 | 4.33 | 5.22 |
| Liquid phase | 170 | 5.80 | 7.00 |
| 50-kDa ultra-filtration retentate | 25.20 | 1.15 | 1.39 |
| 1-kDa ultra-filtration retentate | 26.50 | 0.64 | 0.77 |
| Nano-filtration retentate | 31.80 | 2.33 | 2.81 |
| Cumulative recovery B | 81.25 |
A Expressed as % on a dry matter basis. B Cumulative recovery was calculated based on the mass balance (%) of all resulting fractions (The values associated to both liquid after decantation, and liquid after centrifugation, were not taken in account in this calculation since these fractions were used as starting steps further in the process).
